About this 3D model

This is a simple spring/ball latch to keep a door closed but not locked. I am using it on a full size door but it is often used on cupboards and cabinet doors. The trapped nut and the bolt allow adjusting the tension of the spring. The hardware I used is: * 1 x M3 bolt (20 or 25mm long) * 1 x M3 nut * 1 x Spring (I am using one from an [IKEA PRESSA clothespin](http://www.ikea.com/us/en/catalog/products/30108607/)) * 1 x 11mm steel ball
